FIXED VOLTAGE REGULATOR LM78LXX
3-TERMINAL 0.1A POSITIVE VOLTAGE REGULATORS
This series of fixed-voltage monolithic integrated-circuit
voltage regulators is designed for a wide range of
applications.
These applications include on-card regulation for
elimination of noise and distribution problems associated
with single-point regulation.
In addition, they can be used with power-pass elements
to make high current voltage regulators.
Each of these regulators can deliver up to 100㎃ of output
current.
The internal limiting and thermal shutdown features of
these regulators make them essentially immune to overload.
When used as a replacement for a zener diode-resistor com-
bination, an effective improvement in output impedance
can be obtained together with lower-bias current. ORDERING INFORMATION

1. To specify an output voltage, substitute voltage for "XX"
2. Bypass capacitors are recommended for optimum stability and transient response
and should be located as close as possible to the regulators.
